from nltk.stem.snowball import SnowballStemmer stemmer = SnowballStemmer("english") word = "running" stemmed_word = stemmer.stem(word) print(stemmed_word)In this example, we first import the SnowballStemmer from the nltk.stem.snowball package. We then create an instance of the SnowballStemmer for the English language. Finally, we use the stem() method of the stemmer to get the stemmed version of the word "running", which returns the stem "run". Therefore, it can be concluded that the package library used for this example is nltk.stem.snowball.
